Ford 6.7L Power Stroke Diesel :: Vibrating Sound When Turned Steering Wheel Slightly To The Right On Highway
May 21, 2015
For the past month or so I have had something strange going on. When driving between 65 to 70 on the highway, I've turned my steering wheel slightly to the right and if there is a cross wind or head wind there is a vibrating sound. And it does get loud. I don't really feel it in the steering wheel. Only when there is a wind. I haven't done anything new to the truck since winter.

So, on my way home from checking out a house all of a sudden the truck started vibrating when getting on the highway. Then it got worse quickly. So I pulled off at the next exit and pulled into a parking lot, the truck shuddering badly any time I pressed the fuel pedal. Had it towed to my local Ford dealer. I'm thinking torque converter/transmission, but I freely admit I don't know. Here's what I think is pertinent info-
1. I bought it at 84k miles, now 122k. Oil changed every 5k, fuel filters every 10k, coolant every 20k, trans fluid every 20k. Don't kmow what was done first 84k miles before I bought it.
2. Driveshaft rebuilt one year ago. Both fr and rr diff fluids changed a few months ago, along with transfer case fluid.
3. When in park or neutral engine revs perfectly smooth. When placed in gear and fuel is added it starts to shudder, getting worse as revs go up. Does not vary with road speed, only with engine speed and load into transmission.
4. There are no codes at all. All temps were normal. Engine oil and trans fluid level normal.
5. A few months ago when coming home from a trip I suddenly had the same symptoms about 3 miles from home, but not as bad as today. Made it home taking it easy and went to bed. I was exhausted from a long day of driving and when I test drove the truck the next morning to check it out it was smooth as could be, so I thought maybe I imagined it. Symptoms did not reappear until today, a few months and several thousand miles later.

I had a friend do an alignment on my truck yesterday. Afterward, we tried to center the wheel the best we could in the shop. But when I drove it home I noticed that when going straight, the steering wheel is ever-so-slightly turned to the right. Is there and easy way to adjust this without me going back to the guys' shop and bugging him again? I know the alignment is dead nuts, but the wheel is just a tad off.

There's a pump or ?? I'm not sure . Our "11 6.7 is making whining vibrating sound coming off passenger side , front of valve cover . Not sure what this is . Nothing I'm searching is telling me n I'm not best with diesels .

Noticed the steering wheel shakes just slightly at highway speeds. Happens to me when I'm at around 65-70mph and above. It's just very slight, so I really wasn't thinking its an alignment issue at all. I didn't know if this was a bit normal for these B7s or what. I've had alignment issues in cars before and this just doesn't feel that bad, but its enough to give me pause.

Just rotated my tires this weekend and noticed today that the steering wheel has a vibration in it at highway speeds, 65-70mph. It did not do this at all before I rotated the tires, why it's doing it now? Tires are fairly new and Bridgestones H/Ts.
I know my rotors are warped and need replaced but the vibration I'm referring to is when I am not braking.

I have a slight steering wobble (not really shaking/vibration) at higher speeds and only when I turn the wheel to the left or right a little (maybe a 1/2 inch). If I am driving straight down the highway it is smooth at any speed 40-90mph no issues. If I move the wheel to the left or right I feel the the wobble in the wheel. If I go back and forth a little, constantly, with the wheel it continuously wobbles.
I had recently addressed some other vibration issues by installing new LCA #2, continental DWS tires, and had the front end aligned (front -.3L and -.5R for camber, Rear -1L and -1R camber, front and rear toe set to -.07, if I recall). I couldn't really remember if I felt this wobble before because the tires and LCA's needed to be done badly. I am not sure if I should replace the struts either since ride feels good.
My steering feels darn good and responsive at low speeds and does not wobble when turning the wheel slightly. I have purchased new oem steering rack bushings but have not installed them yet (purchased as a preventive maintenance part when i had some free time, before I discovered this issue).
I have read a few threads about alignment of the steering rack causing issues if it is not perfectly centered. Not sure if that would cause anything like this. Love driving the car but the wobble is rather annoying when i turn the wheel a little to change lanes at 75mph.

Is there any quick fix for this? My steering wheel is slightly turned when the wheels are pointing straight. I thought a wheel alignment would fix this, but it didn't.

Over the last few days, I've noticed that my steering wheel makes a rubbing / vibrating sound as I turn the wheel and press the brakes. This is happening as I'm pulling in or out of a parking spot, or when I slow down to take a wide turn.

I've been noticing some weird, very subtle engine sound changes while driving at highway speeds lately. Something almost like surging, but not. I don't know how to describe it. I might try to make an audio recording next time I take it out so I can explain it.
Anyway, I don't know why but ICP popped into my head. Maybe, for some reason, the engine was varying ICP causing the surging sounds.
So I hooked up AE and did a test. I've attached a screen shot.
With my idle speed actuated as high as it will go, and ICP actuated as high as it can go, I can only get a pressure of about 1450 PSI. I always thought ICP should go higher than that. I seem to recall reading somewhere around 3600 PSI.
So am I misinformed, am I reading the data wrong or do I have a problem? How high should Injector Control Pressure go? I missed it in the screen shot, but ICP is actuated to 100%.

Was on the way home today and was taking a long sweeping left-hand curve at 60 and got a horrible shake in the steering wheel. Kinda scared me a bit and let out of the throttle a bit. Didn't happen after and never has before. I'm under the impression it is more shocks maybe then steering, Reason I say that although I don't get a lot of bounce if the road isn't perfectly smooth I can really tell it. What do ya'll think?

I've got a 'new to me' 4" Lift 6.0L PSD Diesel, 2005. At 60 mph, especially 75 mph, there's some 'play' or float feeling in the steering wheel. Is that a normal thing for a 4" lift? and nothing to worry about? (the dealer that sold it said they put new ball joints in it. No cheap shock problem, right?)

I have a 2015 Platinum Superduty that came with a heated steering wheel but cannot figure how to turn it on and off. I have looked for a dash switch and in the climate portion of the touch screen with no luck. My wife's car has a simple dash mounted switch and also a temp sensor that cuts it on automatically when cold. No such luck with truck.

Looking to swap out the vinyl wheel with a leather-wrapped one from a Lariat. I assume that this will be a direct swap but wanted to poll the audience to make sure I'm not overlooking anything.

2013 F250 with 36K miles. Just in the past 2 months I've noticed my steering wheel is disintegrating at about the 12:30 position. No possibility of diesel/chemical transfer to the surface.

I have been ignoring a slight aggravating shake in the steering wheel for quite some time. I just assumed tire out of balance or slightly warped front rotor or some ball joint work due to approaching 80,000 miles. Well the slightly warped rotor became much worse so i dove into the front brakes. Long story short it ended up being the rear brake rotor/caliper sticking transferring the vibration to the steering wheel. With two other vehicles to maintain i missed/neglected the rear hardware on the truck. So keep the rear brake hardware on your radar for a front end shimmy. Its gone now and a pleasure to drive again. I do have the crew cab and 8' bed which gives the rear end a long lever.

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

I know that to remove the lower knee panel under the steering wheel all that has to be done is to pull it off and the attachment snaps will pop free. However, How do I go about removal of the dash panel to the left of the steering wheel? This would be the narrow panel that also houses an ac vent, headlight and I believe it is the adjustable pedal control.

I have an 04 6.0 psd and if I am stopped in drive with the brake pedal down I can't turn my steering wheel at all. If the truck is in park and my foot off the brake pedal I can turn the steering wheel both ways just fine. When I am driving I don't have any problems with the steering. I have checked the power steering fluid and it is full. This makes it kind of hard when I am trying to pull in and out of parking spots. What could be causing this and what the solution would be to fix it?

This may sound petty, but I would like to have the radio controls on the left side of the steering wheel of my 2012, instead of the cruise control. I guess the main question is how the wire harness is set up. Do the wiring can be re-routed to accommodate the switch?
Also, I want to smooth out the ride a tad so as to lessen the amount of griping from from the passenger seat. What is acceptable in lowering the tire pressure to allow a better ride without compromising tire wear? The factory specs are 65 psi. My truck is a 2012 fx4 Lariat with the 6.7
